For the above embodiment, after the receiving step receives the relevant request, the generating step is further performed to generate the first smart contract related to the request, and the issuing step is issued to the block chain. That is to say, the above embodiments can solve the problem of dependence on information in the modern manufacturing field, especially how to securely and credibly obtain relevant information through blockchain technology when the first manufacturer does not have the first information. It is for this reason that the above-mentioned method also needs a notification step, a signing step and a sharing step, wherein the notification step carries out extensive notification to potential other parties, and when there are other parties capable of responding to the smart contract, the method further passes The signing step signs a smart contract between the first manufacturer and other parties, so that blockchain-based technical means ensure that all parties recognize the trust relationship, shared records, and even information copyright ownership, while the sharing step responds to the signing step and passes A secure connection shares the first information between the first manufacturer and other parties.

It can be seen that, through the above embodiment, the first manufacturer can exchange information with others through the blockchain-based information sharing method, thereby supporting the production and business operations of the first manufacturer and integrating information from other parties.

It can be understood that the first information may be some kind of knowledge, experience or other data needed in production, or may be some kind of knowledge, experience or other data needed in business operation. The first information may be used to improve the industrial design of the product, may also be used to improve the performance of the product, and may also be used to improve the user experience of the product.

It should be emphasized that, as known to those skilled in the art, the above-mentioned embodiments of the present disclosure are to make full use of the security and credibility of the blockchain technology, and the security and credibility of the blockchain technology come from its decentralization The characteristics of globalization and P2P (also known as point-to-point, or peer-to-peer) characteristics. The above embodiments make full use of the equal computer status of each node in the P2P network, each node has the same network power, and there is no centralized server. The information sharing method uses blockchain technology, which means that the information The sharing method implements the signing of smart contracts and information sharing by the nodes of the relevant parties through the relevant protocols of the blockchain, thereby realizing the standardization and interoperability of the framework, and effectively solving the situation where the method includes many participants. Balance the interests of all parties between the ownership of the first information and the sharing of the first information, and then achieve complementary advantages, so as to greatly improve the production and business capabilities of the first manufacturer.

As far as the above-mentioned embodiments are concerned, those skilled in the art know the generally accepted definitions of the smart contracts therein, and details are not repeated here.

In another embodiment, said method establishes said secure connection through a signing step or a sharing step.

As far as this embodiment is concerned, the establishment of the secure connection can be established through a signing step or a sharing step. It can be understood that after the smart contract is signed, the signing step may further establish the secure connection, or the sharing step may establish the secure connection through the sharing step before initiating the sharing.

In another embodiment, the first smart contract is established through a template.

As far as this embodiment is concerned, establishing corresponding smart contracts through templates is helpful for faster and standardized generation of smart contracts. For example, the method may pre-establish an association relationship between a corresponding request type and a template, and when a request of a specific type is received, a corresponding smart contract is quickly established through a corresponding template through a generating step. The smart contract is established through the template, which facilitates the implementation of the technical solution of the present disclosure and is also conducive to further improving user experience. It is easy to understand that this disclosure does not exclude the following situations: if there is no suitable template in the method implementation process, a user or administrator can also create a suitable template and add it to the corresponding system or method. It can be understood that this addition Approval may be required for implementation.

Furthermore, an example of the first information sharing request and smart contract template is given below:

First Information Sharing Request:

id: first manufacturer

Request: Request a list of mobile phone full-screen suppliers

Smart contract template:

Type: mobile phone field

username: id

Contract parameters: {

File Name: Digital Certificate.pdf

File Path: C:\Certificates\

}

Contract content: request

Contract code: info_contract.sol

Obviously, in the above template example, the content of the "request" field of the first information sharing request corresponds to the "contract content" in the template, and the content of the "id" field of the first information sharing request corresponds to the "username" in the template , and the template invokes the corresponding digital certificate to issue the smart contract by default. It can be understood that the above is only an example, not a limitation, and its purpose is to apply templates and quickly generate smart contracts.

In another embodiment, the other party is a second manufacturer or logistics provider or distributor.

As far as the above-mentioned embodiment is concerned, in the field of modern manufacturing, there is a situation where the first manufacturer may be a manufacturer of a certain link, and the first manufacturer is likely to need support from upstream and downstream supporting links in production or business.
